INVENTOR Seymour 5, Fade) j'-IZ l2 WWW/MW ATTORNEY United States Patent 3,266,843 DEMUUNTABLE CHAIR Seymour S. Feder, West Grange, N.J., assignor of onehalf to Maurice Davis, Brooklyn, N.Y. Filed lune 14, 1965, Ser. No. 463,769 Claims. (Cl. 297440) This invention relates generally to demountable chairs, and particularly to such chairs in which the arms clinch the back and base together.

It is an object of the invention to provide a chair which, in unassembled state, may be placed in a compact box for shipment, thereby reducing sale price.

Another object is to provide a chair which is easy for the purchaser to assemble.

Yet another object is to provide a chair whose base and back are locked together in assembled state by an arm.

A still further object is to provide a chair unit readily adaptable to multipart assemblies, as in love-seats, couches, and loungers.

These objects and advantages as well as others may be attained by the device shown by way of illustration in the drawings, in which:

FIGURE 1 is a side elevational view of the demountable chair;

FIGURE 2 is a perspective view of the arm of the chair;

FIGURE 3 is a rear view of the back and seat prior to engagement;

FIGURE 4 is a partial vertical, sectional view taken on the line 44 in FIGURE 1.

Assembled chairs are bulky, and costly to ship. It has been found that a demountable chair may be cheaply and easily shipped, with the parts fitted compactly into a sturdy small box.

Referring now to the drawings in detail, there is provided a generally horizontal seat 11. The seat 11 is a generally rectangular frame made of wrought iron, although many other materials can be used. At the corners of the seat 11, four legs 12 preferably of metal, are attached by welding or in some other suitable manner. They may be detachable, with any well known securing means (nuts, bolts, etc.) for attaching them to the seat 11. At the back of the seat, there are a pair of sockets 14, 14 for a back attached to the seat, and adapted to receive a back as hereinafter set forth. A seat-cushion 15 is placed upon the seat 11, and supported by transverse slats 9, 9 etc.

A back 16 is provided. Its form is an inverted-U preferably of wrought iron. The ends 17, 17 are dimensioned to be inserted in the pair of sockets 14, 14. A back cushion 18 is placed against the back 16 and rests upon the seat-cushion 15. The back and seat are, in this form slidably, or loosely, secured together. The seat has arm sockets 10 on opposite sides, at the bottom. The back 16, likewise has sockets 21, 21 at the rear.

The seat 11 and back 16 are clinched together by an arm 19, for each side. The arm 19 is preferably made of metal, and is tempered to make it semirigid, and slightly deformable. It is preferred that the arm 19 be resilient, so that the ends may be inserted in sockets. The arm has ends 20, 20, which are insertable into the sockets 10, 10. The sockets 21, 21 receive the opposite ends 20, 20 of the arms 19. Since the arm-sockets 10, 10 on the base 11 are oriented in nonparallel relation to the armsockets 21, 21 on the back 16, either of the ends 20, 20 (whichever is last inserted in the arm-sockets 10, 21), must be deflected to be inserted in the corresponding socket. In this manner, the semi-rigid arm will normally clinch the back 16 and base 11 together. The resilient character of the arms 19 permits them to be deflected for end insertion, and also enables the arm 19 to hold the base 11 and back together. The ready assembly of the demountable chair enables it to be shipped demounted in a compact box, to be easily assembled by the purchaser.

While there has been shown in FIGURE 1, dotted lines representing one particular end of the arm 19 deflected for insertion in the socket 10, it will be understood that the opposite end may also be deflected (not shown) to permit insertion secondly, when the one end has been inserted first in a socket.

The foregoing description is merely intended to illustrate an embodiment of the invention. The component parts have been shown and described. They each may have substitutes which may perform a substantially similar function; such substitutes may be known as proper substitutes for the said components and may have actually been known or invented before the present invention; these substitutes are contemplated as being Within the scope of the appended claims, although they are not specifically catalogued herein.

What is claimed is:

1. A demountable chair comprising:

(a) a generally horizontal seat;

(b) a plurality of legs depending from the seat;

(0) a generally upstanding back attached to the seat;

(d) a first arm-socket on the back;

(e) a second arm socket on the seat;

(f) a resiliently deformable arm having its opposite ends inserted in the first and second arm sockets;

(g) the resilience of the arm normally urging the opposite ends thereof into clinching engagement with the said sockets.

2. A demountable chair comprising the article according to claim 1, and

(a) the insertion axes of the sockets being at least 3. A demountable chair comprising the article according to claim 1, and

(a) the first and second arm sockets disposed in nonparallel relation to each other.

4. A demountable chair comprising the article according to claim 1, and

(a) a pair of sockets on the seat;

(b) the attachment of the back to the seat accomplished by the opposite ends of the back inserted in the pair of sockets.

5. A demountable chair comprising the article according to claim 1, and

(a) a back cushion and a seat cushion disposed respectively against the back and seat.
